The oldest Tendo sister in Ranma 1/2. She is the most domestic of the three sisters and handles almost all of the household cooking and cleaning in the Tendo household. Kasumi is also mildly oblivious to the world around her and greets everything with a cheery attitude.

Ryoga is the rival of Ranma. He has horrible sense of direction and is constantly getting lost on his way to battles, even if they're in his own backyard. He is also cursed to turn into a pig whenever he is exposed to cold water.
